3 Claims.

This invention relates to an improved adjustable window shade bracket, and more particularly to a construction of window shade bracket wherein, when a pair of said brackets are employed for mounting a window shade roller, either of the brackets may be readily adjusted Arelatively to a supporting plate which is attached to a window easement for adapting the pair of brackets to window shades and window shade rollers of different lengths.

Still another aim of the invention is to provide a construction of window shade bracket, adapted to be employed in pairs for mounting a window shade roller, and wherein the roller cannot be detached from the brackets Without releasing and extending one or the other of the brackets to thereby prevent the roller from becoming accidentally detached.

` Still another object of the invention is to provide novel wedge means for clamping the shank portion of the shade bracket relatively to the supporting plate on which it is slidably mounted for retaining the bracket in any one of a plurality of adjusted positions relatively to its supporting plate.

Other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, which illustrates a preferred embodiment thereof, and wherein:

Figure 1 is afragmentary front elevational view of the upper portion of a window easement shown equipped with a pair of window shade brackets constructed in accordance with the invention,

Figure 2 is an enlarged front elevational View of the bracket disposed at the right hand side of Figure 1,

Figure 3 is an end View in elevation of the same looking toward the device from the left hand end of Figure 2,

Figure 4 is an enlarged horizontal sectional view taken substantially along the plane of the line 4-4 of Figure 2, and

Figures 5 and 6 are enlarged vertical sectional Views taken substantially along the planes of the lines 5-5 and 6-5, respectively, of Figure 2.

Referring more particularly to the drawing, wherein like reference characters designate like or corresponding parts throughout the different views, Il) designates generally an adjustable window shade bracket constructed in accordance with the invention, and including a shade bracket member II provided with an opening I2 for receiving a pin, not shown, which projects from the end of a shade roller, not shown. I llce4 portion of the bracket II around the opening I2 is pressed outwardly, as best seen at I3 in Figures 2 and 4, to reduce the frictional engagement between the end of the roller and the outer side of the bracket Il. The opening I2 is shown as being circular, but it may be of any required shape to conform to the shape of the pin that it is to receive, and as in the case of pairs of conventional window shade brackets the adjustable shade brackets Il) will likewise be provided in pairs, as illustrated in Figure 1, and the opening I2 of the bracket member II of one of the adjustable shade brackets I0 will be circular whereas the opening I2 of the other Will be polygonal shaped, or oblong, as in most instances, corresponding to the openings in conventional window shade brackets except that the oblong opening does not open outwardly of an edge of the bracket member, for a reason which will hereinafter become apparent. The bracket member I I is provided with an elongated shank portion lli which is disposed substantially at a right angle to the aforementioned portion of the member I I.

The adjustable shade bracket Iii also includes a supporting or base plate I5 whichis provided with openings adjacent its side edges and intermediate of its ends, designated I5, for receiving fastenings I'I for securing the plate I5 to the top rail of a window easement, I8 adjacent one end and longitudinally thereof. The plate I5 is provided with transverse slots, extending to adjacent its side edges, and one of which is disposed adjacent each end thereof. The portions i9 of the plate I5, which are disposed beyond said slots, designated 2Q, are pressed outwardly to form outwardly olfset guide portions. The shank Iii extends loosely beneath the guide portions IS and over the intermediate portion 2| of the plate I5 and is thereby slidably mounted longitudinally of the plate I5 for slidably supporting the bracket member II relatively to the plate I5 and to the top rail of the easement I3.

A lever 22 is pivotally connected at one end by means of a rivet or other pivot means 23 to the plate I5, adjacent its upper edge. As best seen in Figures 5 'and 6, the rivet or pivot member 23 is countersunk in the back of the plate I5 so that it is disposed flush with the back portion thereof and so that the portion of the plate I5 which engages against the easement IS will provide a smooth, hat surface. The lever 22, when disposed in a depending, perpendicular position will be disposed with one of its longitudinal edges engaging against the inner edge of the innermost guide portion I9, as best seen in Figure 2l. A tapered lug 24 projects from said aforementioned edge of the lever 22 and is adapted to be disposed between the inner side of the innermost offset portion I9 and the outer side of a portion of the shank I4 to provide a wedge for clamping the shank I4 relatively to the plate I5 and particularly to the intermediate portion 2I thereof. A knob 25 is attached to and projects outwardly from the lower, free end of the lever 22 and provides a finger hold for swinging the lever upwardly and outwardly relatively to the plate I5 for releasing the shank I or in the opposite direction for positioning the lever in the position, as seen in the drawing, for clamping the shank M to the plate I5.

As best seen in Figure l, the adjustable window shade brackets are adapted to be mounted in pairs, one adjacent each end of the upper rail or" a window easement, such as shown at I8 in Figure l, with the bracket members II projecting outwardly from the inner side of the Casement I8, substantially at right angles to their shank portions Iii which are disposed substantially parallel to the Casement I8. The members II likewise are disposed to form the adjacent ends of the adjustable window shade brackets II) and are adjustable relatively to one another for accommodating the pair of brackets I@ to window shades and rollers of different lengths. As previously mentioned, the opening I2 of one of the bracket members Il will be circular while that of the other will be oblong or polygonal shaped, and by swinging the levers 22 outwardly and upwardly, the shank portions I4 will be released so that the members Il vmay be extended relatively to each other to permit the shade roller to be disposed therebetween andto permit the pins at theends thereof to be inserted in the openings I2. The members II may then be adjusted simultaneously relatively to their supporting plates I5 for centering the roller and shade, not shown, relatively to the side rails of the easement IB, after which the levers 22 are swung downwardly and inwardly to position the wedge members 24 for clamping the shanks I4 in the plates I5. 1t will be obvious that the wedge members 2d will prevent the members II from moving relatively to the plates Irwhile they are in clamping positions, as illustrated in Figures 4 and 6, to thereby positively prevent the shade roller from being released without releasing the wedge members 2d. The wedge members 2li will prevent either inward or outward movement of the Shanks I4 relatively to the plates I5 and when the shade roller is disposed between the 'members II it will of course, likewise prevent the shanks I4 from moving inwardly of one another. It will be readily apparent that a pair of adjustable window shade brackets IG when mounted, as illustrated in Figure 1, will provide means for mounting shade rollers of a wide variety of lengths without removing either of the supporting plates I5 from the casement I8 and will at the same time permit shade rollers and shades of any of the various sizes to be correctly centered relatively to the side rails of the Casement I8.

If desired, the window shade brackets Ill, as shown in Figure l, can be reversed so that the shade bracket members II will form the remote ends thereof to thereby position the other portions thereof beneath the shade and roller. When so arranged, it will be necessary that the portions I3 project from the inner sides of the members I I, instead of from the outer sides thereof, as illustrated, so that said portions I3 will extend toward the ends of the shade roller.

Various modications and changes are contemplated and may obviously be resorted to as only a preferred embodiment of the invention has been disclosed.

I claim as my invention:
